A conformal boundary for space-times based on light-like geodesics: the 3-dimensional case
A. Bautista, A. Ibort, J. Lafuente +1
A new causal boundary, which we will term the -boundary, inspired by the geometry of the space of light rays and invariant by conformal diffeomorphisms for space-times of any di…
Extended Scaling in High Dimensions
Bertrand Berche, Christophe Chatelain, Chania Dhall +3
We apply and test the recently proposed "extended scaling" scheme in an analysis of the magnetic susceptibility of Ising systems above the upper critical dimension. The data are ob…
The Red Queen visits Minkowski Space
Robert J Low
When Alice went `Through the Looking Glass' [1], she found herself in a situation where she had to run as fast as she could in order to stay still. In accordance with the dictum th…
Light Sheets and the Covariant Entropy Conjecture
Robert J. Low
We examine the holography bound suggested by Bousso in his covariant entropy conjecture, and argue that it is violated because his notion of light sheet is too generous. We suggest…
Causal monotonicity, omniscient foliations and the shape of space
Steven G. Harris, Robert J. low
What is the shape of space in a spacetime? One way of addressing this issue is to consider edgeless spacelike submanifolds of the spacetime. An alternative is to foliate the spacet…
Speed Limits in General Relativity
Robert J Low
Some standard results on the initial value problem of general relativity in matter are reviewed. These results are applied first to show that in a well defined sense, finite pertur…
